// Arc

The Stack Arc Builders Ship On

Connect to Arc Mainnet and Testnet with low-latency RPC, full archive data, debug and trace APIs, and real-time Streams. The complete Arc data stack, managed from a single Quicknode dashboard.

// Supported networksMainnetTestnet
// 99.99% uptime SLA17+ global regions
// Unified Arc Stack

Mainnet, Testnet, Archive, and
Streams in One Dashboard.

Arc builders need more than basic RPC. Quicknode runs the full surface: low-latency JSON-RPC on Arc Mainnet and Arc Testnet, full archive with debug and trace, and real-time Streams, all from one dashboard.

Data Access for Every Arc Workload

Query, subscribe, and stream Arc data with low latency. From a single eth_call to billions of rows of historical logs, you get the right interface for the job.

JSON-RPC over HTTPS and WSS on Arc Mainnet and Arc Testnet
Full archive nodes with debug_traceTransaction and debug_traceBlockByNumber
Streams for backfill and real-time Arc blocks, logs, and traces
Webhooks for push notifications on addresses and events
WebSocket subscriptions with eth_subscribe for new blocks and logs
// Build & Ship

EVM Tooling You Already Know

The Ethereum toolchain you already know works unchanged on Arc. Deploy contracts, manage endpoints, and ship from one Quicknode account.

Deploy and verify Solidity contracts with Hardhat, Foundry, and Remix
Token authentication, rate-limiting, JWT, and whitelisting on every endpoint
ethers.js, web3.js, viem, and @quicknode/sdk supported out of the box
Archive access with debug and trace for indexing and simulation

// Every Arc Data Pattern

The Full Data Suite.
Every Arc Data Pattern.

Multiple ways to access Arc data, from a single eth_call to real-time streams. Pick the interface, ship faster.

Arc JSON-RPC

Standard JSON-RPC over HTTPS and WSS on Arc Mainnet and Arc Testnet. Every EVM method supported, including eth_call, eth_getLogs, eth_getBalance, eth_sendRawTransaction, and eth_subscribe, with predictable rate limits.

Full Archive History

Full historical Arc state with no pruning on Mainnet and Testnet. Query any block, balance, or contract state from genesis over HTTPS and WSS.

Streams

Backfill and real-time Arc blocks, logs, and traces delivered to your datastore with guaranteed reliability. Filter upstream, receive only the data you actually need.

Webhooks

Event-driven alerts with guaranteed delivery. Subscribe to specific addresses, event types, or onchain conditions.

Debug & Trace

Trace transactions and inspect execution with the debug and trace namespaces, including debug_traceTransaction, debug_traceBlockByNumber, and trace_block, for deep analysis and reliable indexing.

WebSocket Subscriptions

Subscribe to new Arc blocks and logs over a persistent WSS connection with eth_subscribe. Push updates the moment they land, with no polling.

// Built for EVM Developers

Your Ethereum app runs on Arc.

Arc is an EVM-compatible layer 1 from Circle, so the tooling you already know works unchanged. ethers.js, web3.js, viem, Hardhat, and Foundry all hit a Quicknode Arc endpoint the same way they hit Ethereum. Same methods, same SDK, just a different RPC URL.

No rewrites

Point your existing Ethereum codebase at a Quicknode Arc endpoint and deploy. Contracts, libraries, and tooling carry over.


Same JSON-RPC methods

eth_call, eth_getLogs, eth_sendRawTransaction, and eth_subscribe all behave exactly as they do on Ethereum.

// Same methods, same SDK. Arc is EVM compatible.
// Add Arc to MetaMask

Connect MetaMask to Arc in seconds.

Open MetaMask, go to Settings, Networks, Add Network, and enter your Quicknode Arc RPC URL with the details on the right. Save, and MetaMask routes through your private Quicknode endpoint instead of a rate-limited public RPC.
